1.Application Purpose

When single-phase grouding fault occurs in the power grid, this system instantly adjust the inductance to compensate the grounding capacitance current. Making fault point residual is less than 5A eventually.

2.Structure

The THT-PXHK including 3 parts as following:

2.1Grounding transformer （dry or oil-immersed type）

2.2 Biasing magnetic arc-suppression coil（dry or oil-immersed type）

2.3 Computer control cabinet

3.Features

 3.1The resistor cabinet adopts Al-Zn coated plate, stainless plates or cold-rolled steel plates, featuring beautiful appearance and corrosion resistance.

  3.2Stable reliable and endurable

  3.3Higher regulation precision and fast reliable

  3.4Dynamic compensation with damping resistors not required

  3.5Electric controlled stepless continuous and static adjustability

  3.6Simple structure, space-saving, low failure rate, easy maintenance and basically free of maintenance.
